To all 'whom zt concern:

yBe it known that I, GEORGE E. PICKUP,

a' Newark, in the county of Licking and tate 'v ofOhio, have invented certaln newand u seful Im rovements inA Gas-Burners, of which citizen of the United States, residin -to provide a gas burner wherein'the burner head, the supply tube and the mixing bowl are formed up from a pair of. sheet metal parts of complementary shape having the1r meeting edges secured together. A

A further object of the .invention is' to provide a gas burner having a novel arrangement of intercommunicatlng chambers and conduits -which will rapidly distribute the mixture of air and gas throughout vthe entire burner head.

The invention also refers to the detalls of construction which will be more fully pointed out in the following description.

In the accompanying drawings,' Figure 1 is a top plan v1ew of a burner embodying the features of my invention. Fig. 2 1s` a sectional view taken on line 2-2 of Fig. 1. Fi 3 is an Vend elevational view.

n the preferredl embodiment of my 1nvention illustrated in the accompanylng drawings, l indicates a burner head, 2 a mixing bowl and 3 a supply conduit connecting them. These parts are formed up from two substantially similar pieces 4 and 5 of suitable sheet metal. Each piece is formed to make one-half of the mixing bowl, supply conduit, and burner head.

When the pieces are placed backto back, the angular edges 6 and 7 of said pieces or half sections .lie parallel and close to each other and are secured together to form 'a gas-tight joint. In the present instance, the

edges 6 on the top piece are wider than the edges 7 and are bent aroundl and under the latter as shown clearly in Fig. 2.

The burner head 1 is provided with gas outlets 8 by perforating the piece 4 only. These outlets are slightly raised above the surrounding surface to prevent liquid that may be accidentally spilled on the burner 1flroli draining into the interior of the burner ea l Herein I have shown the burner head in the form of two annular concentric chambers 9 and 10 joined by the communicating radial chambers or conduits 11 providing a central opening 12 anda plurality of arcuate openings 13. In provlding these chambers each section 0f the head is pressed to form troughs orconcavities of' generally semi-cy- Y Y lindrical shape in cross Vsection arranged to match the troughs of the other section.

By reason of the formation of the burner head 1 and supply conduit 3 in similar sections, the supply conduit is disposed in theA same lateral plane as the annular chambers 9 and 10 and thus communicates directly Y with the outer chamber 9; and the conduits 11 also lie in the same lateral plane as the chambers 9 and 10 which they connect. Preferably the supply conduit communicates with the chamber 9 (at a vpoint substantially midway between' two connecting conduits 11, but the ends 'of each of the conduits 11 are rounded or flared outwardly and are spaced a relatively short distance from the opposite sides of the supply conduit, so that the mixture of gas and air passes rapidly from one chamber to the other. Thus the air and gas mixture becomes rapidly distributed throughout the entire burner head.

being suitably closed by a shutter valve 14.'

The mixing bowl is provided with depressions 15 in which means upon the shutter valve are seated for securing., the same to the bowl.

The shutter valve comprises a stationary outer disk plate 16' provided with a central opening 17 and an inturned tlange`18 outlining the same.V The plate is sectorially apertured as at 19 and on its outer edge carries an inturned ilange 20, a portion of which is cut away asat 21 (see Fig. 3) for a purpose to be described hereinafter. Herein I have shown the seamed edges 6 and ft' on the bowl sections cut away as at 22 so that the inturned flange 20 may embrace the bowl edge. Integral with said flange 20 are lugs or ears 23 which `when pressed into the bowl depressions 15 secure the outer disk to the bowl. A regulating member is herein shown as a disk plate 24 which is similarly apertured. This second disk is rotatable upon the inturned flange 18 (see Fig. 3) between the outer disk plate 16 and the mixing bowl 2. The rotatable disk plate has .an outwardly extending lug 25 forming a handle by which the plate is rotated to control the Openings in the fixed disk plate 16 in the well-known manner of shutter valves. The cut-away portion 21, previously referred to, permits the lug or handle25 to extend beyond the peripheral flange 20. The edges of the flange 20 delining the cut-away portion 21 are shown herein as forming stop portions for indicatingk the extreme positions of the rotatable While I have herein described in coiisiderable detail the preferred embodiment of Vmy invention, I would have it understood that I do not intend to limit myself there` by, the scope of the invention being pointedout by the appended clalms. I claim as my invention: 1. A gas burner formed from two substantially similar sections secured together by a' gas-tight joint and comprising inner and outer annular chambers, a plurallty of separate conduits connecting saidvchambersl and having flared ends, and a supply con-v stantially similar sections secured together by a gas-tight joint and comprising inner and outer annular chambers, a plurality of weones radial conduits spacedl apart and connecting' said chambers, and a supply conduit communicatlng directly with the outer chamber substantially midway between two connecting conduits,the two last mentioned condu1ts having dared outer ends 1n substantially direct communication with the supply conduit.

3. A gas burner formed from two substantially similar sections .of sheet metal* 'connecting conduits.

4. A gas burner having, in combination,

a burner head, a mixing bowl, and a connecting supply conduit, formed from two substantially similar sheet metal sections having outwardly protruding edges secured together to form a gas-tight joint, said mixing bowl having valve means for admitting air thereinto including a plate having an inturned peripheral flange fitting over the ends of the sections formingthe bowl, the outwardly protruding edges of the joined sections being cut away adjacent the end of the mixing bowl to enable the peripheral flange on said plate to be slipped over the end of the bowl.

" In testimony whereof, I have hereunto set my hand.

GEORGE E. PICKUP.
